This invention relates to textile spindles such as are used in spinning frames and the like, and more particularly to a spindle of this sort in which a unique arrangement is provided for fitting the spindle blade with bearings and supporting these bearings during operation.

The textile spindle of the present invention may incorporate any conventional form of blade and is arranged for attachment on a spindle rail in the usual manner, but provides a composite or split housing for the spindle blade bearings that is characterized by separate longitudinal portions formed interiorly with respectively matched transverse grooves that constitute seating recesses for the bear' gs upon assembly of the housing lengthwise about the blade below the spindle whorl. By using spindle blade bearings in this construction that are prelubricated and sealed, the split housing can be used to particular advantage in assembling the spindle readily for accurate support of the bearings and a resulting extended service life, while at the same time allowingany maintenance adjustments or replacements to be made easily and rapidly. Also, this spindle construction of the present invention is especially well adapted to accommodate use to resilient rings or boots about the spindle blade bearings to absorb vibration and allow restricted movement of the spindle blade axis to find its axis of gyration during operation.

These and other features of the present invention are described in further detail below in connection with the accompanying drawings, in which:

Fig. 1 is a side elevation of a textile spindle constructed in accordance with the present invention;

Fig. 2 is a similar side elevation partly sectioned along the line 2-2 in Fig. 1;

Fig. 3 is a further fragmentary side elevation corresponding to Fig. 1, but having the lower portion thereof sectioned vertically and centrally; and

Fig. 4 is a bottom end view corresponding to Fig. 3.

Referring now in detail to the drawings, the textilespindle of they present invention as illustrated comprises an upper sheath or filler section 10 suitably fitted with a wear tip 12 and having a spindle whorl 14 mounted at the lower end thereof. This upper sheath or filler section 10 is in turn mounted on a lower blade 16, and constitutes therewith a composite spindle blade, it being understood that the blade 16 might alternatively be extended upwardly and fitted with a whorl for use without any uper sheath or filler section if desired.

The spindle blade 16 has bearing units 18 and '20 fixed thereon in spaced relation below the whorl 14,-and these bearing units 18 and 20 are preferably fitted peripherally with resilient rings or boots as at 22 and 24 for the purpose previously mentioned. These resilient boots 22 and 24 should be non-oxidizing and oil resistant, and are preferably formed of a synthetic rubber material such as neoprene or Buna S. Also, as previously mentioned, the bearings 18 and 20 should be of the prelubricated and sealed type for employing the present invention to the best advantage. 1

The 'comp'osite or split housing provided according to the present invention for supporting the spindle blade bearings 18 and 20 is indicated generally in the drawings by the reference numeral 26, and is shown as comprising complementary housing portions 28 and 30 that are exteriorly threaded to" receive the usual form of washer 32 and lock nut 34 for clamping the textile spindle in the usual inann'er'on 'a'spindle rail against matched shoulders formed respectively on the housing portions at 36 and 38.

Interiorly, the complementary housing portions 28 and 30 are formed with matched transverse grooves as at 40 and 42 that are spaced therein and proportioned to form circumferential seats for the bearing units 18 and 20 when the housing portions 28 and 30 are assembled lengthwise about the spindle blade 16 below the whorl 14. Assembly of the housing portions 28 and 30 is provided for by arranging dowel holes 44 adjacent the lower end of one housing portion 28 and locating bosses 46 to fit these dowel holes 44 when the housing portions 28 and 30 are mated. When properly located in this manner assembly screws are easily inserted adjacent the top and bottom of the composite housing 26, as at 48 and 50 to fix it in operating relation.

By this arrangement it is possible to form the transverse seating grooves 40 and 42 in the housing 26 for close and accurate support of the spindle blade bearings 18 and 20, because the composite or split form of the housing 26 allows seating of the bearings 18 and 20 directly in place in the course of assembling the housing portions 28 and 30, rather than requiring a seated position for the bearings 18 and 20 to be found blindly as is necessary when a tubular housing is used. This feature is of further particular adavntage when the resilient boots 22 and 24 are employed on the housing portions 18 and 20, because these boots are easily displaced during seating of the bearings. In addition, the composite housing 26 of the present invention provides fior easy access to the spindle blade bearings 18 and 20 whenever necmsary during operation and thereby substantially simplifies maintenance problems as well as providing a more serviceable spindle construction.

The present'invention has been described in detail above for purposes of illustration only and is not intended to be limited by this description or otherwise except as defined in the appended claims.

I claim:

1. A textile spindle comprising a blade, a whorl thereon, bearing units fixed on the lower portion of said blade below said whorl, and a composite base forming a housing' about the lower portion of said blade and providing a composite seat in which said bearing units are fixed upon assembly of said composite base.

2. A textile spindle comprising a blade, a whorl thereon, bearing units fixed in spaced relation on the lower portion of said blade below said whorl, and a composite base surrounding the lower portion of said blade and characterized by separate longitudinal portions formed interiorly with respectively matched seating recesses for said bearing units.

3. A textile spindle comprising a blade, a whorl thereon, bearing units fixed in spaced relation on the lower portion of said blade below said whorl, and a composite base formed by a pair of complementary housing halves assembled lengthwise about said lower blade portion and formed interiorly with respectively matched transverse grooves comp ositely supporting said bearing units.

4. A textile spindle comprising a blade, a whorl thereon, bearing units fixed in spaced relation on the lower portion of said blade below said whorl, said bearing units being prelubricated and sealed, and a composite base formed by complementary longitudinal housing portions assembled lengthwise about said lower blade portion and having respectively matched transverse grooves therein forming circumferential seats for said bearing units upon assembly of said composite base.

5. A textile spindle comprising a blade, at whorl thereon, upper and lower bearing units fixed in spaced relation on said blade below said whorl,. said bearing units being prelubricated and sealed and being fitted peripherally with resilient boots, and a composite base formed by complementary longitudinal housing portions assembled lengthwise about said blade below said whorl and having respectively matched transverse grooves therein forming 4 V circumferential seats supporting said bearing units at the resilient boots thereon upon assembly of said composite base.
